Abstract

In order to increase the data volume to be transmitted in a digital broadcast transmitter network system operating in accordance with the DAB principle, in which, after appropriate data reduction, the digital programmes to be transmitted via the individual transmitting stations are coded in accordance with the COFDM method and modulated, the data of the digital audio and/or video programmes are included in a number of COFDM signal packets and transmitted via the transmitting station and/or two or three 4PSK-COFDM coders, the outputs of which are combined via an acting stage, are used for generating the individual COFDM signal packets. The increased data volume can be supplied via digital satellite transmission channels in accordance with the DSR principle with a higher-order modulation. <IMAGE>
